Dr.Less failed to consider the directionality problem, which arises when the direction of causality between variables is unclear. In this case, it is not clear whether depression caused the withdrawal from nondepressives or if withdrawal from nondepressives caused the depression. The later research suggested that the latter was more likely the case, meaning that depression was a result of withdrawal from nondepressives rather than the cause of it.
